Leaf-sheaths tight; longer than adjacent culm internode; pilose; with tubercle-based hairs; outer margin hairy. Ligule a fringe of hairs; 0.5 mm long. Leaf-blade base broadly rounded; without a false petiole, or with a brief petiole-like connection to sheath. Leaf-blades spreading; linear, or lanceolate; 1-4 cm long; 1-6 mm wide; membranous. Leaf-blade midrib indistinct. Leaf-blade surface pilose; hairy on both sides; with tubercle-based hairs. Leaf-blade margins tuberculate-ciliate. Leaf-blade apex acute, or acuminate.
    Inflorescences
    Inflorescence a panicle; embraced at base by subtending leaf. Panicle open; ovate; 2-6 cm long. Primary panicle branches spreading; simple. Panicle branches capillary; flexuous; smooth, or scabrous; with scattered hairs; with tubercle-based hairs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-2 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; compressed slightly; acute; 2-2.3 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; compressed slightly; acute; 2-2.3 mm long; falling entire.
    Glume
    Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.25 length of spikelet; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate, or obtuse. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface smooth, or asperulous; rough above. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; smooth, or scaberulous; rough above; acute. Fertile lemma elliptic; dorsally compressed; 1.5 mm long; indurate; shiny; without keel. Lemma surface striate. Lemma margins involute. Lemma apex acute. Palea involute; indurate.
